PUMP.

Application filed December 8, 1921.` Serial No. 520,823.y

To u/'Z vri/wmf 'it may concern.'

Be it known that I, Jnnnr D. NIKON, citizen oi the United States,residingl at Houston, in the bounty oi Harris and State of H Texas, haveinvented certain new and useful Improvements in a Pump, of which thefollowing is a spec-ilication.

This invention relates to new and useful in'iproveinent-s in a pump. iOne object ot the invent-ion is to provide a pump specially adapted foruse in pumping oil from oil wells, and provided with sand pocketsdisposed to receive sandV and other sediments with which the oil isladen.

Another object of the invention Vis to pro vide a pump having pockets toreceive the sedii'nentary matter contained in the oil and which, bycollecting said matter, will enable the pump to operate for a greaterlength of 0 time wit-houtcleaninfrthan is the case with pumps now incommon use and which, on account of the consequent reduction of sandfriction will cause a decrease wear on the workingparts and theconsequent lengthen ing of t-he life of the pump.

With the above and other objects in view the invention has particularrelation to certain novel features of construction, operation andarrangement of parts, an example of which is given in this specificationand illustrated in the accompanying drawings, wherein Figure 1 is avert-ical sectional view of the upper end of the pump. V

Figure 2 is a vertical sectional view of the lower end thereof.

Figure 3 is a transverse sectional view taken on the line 3, 3 of Figure1, and

Figure 4e is a side view of a spider einployed.

l Referring now more particularly to the drawings, the numeral 1designates the standing barrel off the pump and the numeral 2 designatesthe working barrel.

l These are connected, at their lower ends, 'bv

means of an anchor 3, to which they are screwed at their lower ends insuch al inanner as to space the latter concentrically within the former.The working barrel is formed of two sections connected by means of a`collar l which has a clearance between it and the standing barrel andis formed with the spider legs 5 which hold the working barrel centeredwith respect t-o the standing barrel. Threaded into the upper may beengaged therewith to withdraw the z pump from the bore.

The lower end of the anchor L has an internally threaded socket 9 intowhich the usual gas anchor (not shown) may be threaded. i

.The upper end of the working barrel 2 is spaced below the bushing 6 andis held centered by means Vof the spider shown in Fig- 4ure 4. As shownthis spider isformed with the legs 10 connected by their upper ends bymeans of the ring 11 and at their lower ends by means 'of the ring Theinside of the lower ends of these legs are oii'set forming the shoulders13. which rest upon the upper end of the working barrel and the reducedlower ends of the legs tit between the standing and working barrels forthe purpose indicated. This spider is held in place by reason of thefact that the lower endV of the bushing 6 is screwed down against thering 11.

The anchor 3 is formed with a fluid passage way 14 into the upper end ofwhich the lower end of the tubular valve anchor 15 is screwed concentricwith and spaced from the working barrel 2 and screwed onto its upper endthere is a nipple formed to receive the valve scat 17 which is heldclamped in place by means oit the cage 18 which is threaded onto nipple16 and which contines the ball Valve 19 controlling said seat. vThevalve mechanism above described, and carried by the anchor 15 is of suchVdimensions, as to form a. cl'L ance `bctween it and the working'barrel.

lilithiu the upper end of the working barrel 2 there is a hollow pluiier .termed theplunger is reciprocated by a suitable pump jack at thesurface of the ground.

The course of the oil is indicated by long arrows and the course of thesand and sedi mentary matter is indicated by the short arrows. f

The suction created by the plunger' dravvs the oil and its sedimentarycontents up through the tubular valve anchor l5 past. the valve 19 andon up through the Working barrel, and the oil above said plunger isforced by it on up through the pipe T and discharged from the Well. Theconstruction herein described provides a deep sand pocket 25 between thebarrels l and 2 and also a sand pocket 26 between the tubular valveanchor 15 and the Working barrel. The sand contained in the oil abovethe standing valve will settle down into the pocket 2G, and theremaining` sand, in the fluid being pumped will sett-le down around theWorking barrel into the pocket 25. This will prevent said sedimentarymatter from clogging the valves and from collecting on the inner Wall ofthe Working barrel. The Wear on the plunger caused by sand friction willthus be greatly diminished as Well as the liability of the clogging ofthe valves. Then the sand pockets have become filled the pump Will haveto be pulled and cleaned, but this will occur at rareintervals thusdispensing with the necessity of frequently pulling and cleaning thepump, a laborious and time consuming operation.

IVhat I claim is:

l. A pump including a standing barrel a Working barrel anchored Withinthe standing barrel and spaced therefrom to form a sediment pocket avalve anchor Within the Working barrel and spaced therefrom forming asediment pocket between them a standing valve Xed to the upper end ofsaid anchor, a reciprocating plunger Within the Working barrel abovesaid valve, means for centering the Working barrel within the standingbarrel, said centering means including a spider formed with legs, ringsconnecting said legs at the upper and lower ends, said legs beingsupported by the upper end of the working barrel, the lower ringsurrounding the working barrel and the upper ring being anchored in thestanding barrel.

2. A pump including a standing barrel a. Working barrel an anchor towhich the lower ends of said barrels are secured, said barrels being`spaced apart to form a pocket between them throughout the length of theworking barrel a tubular valve anchor fixed within the lower end of theWorking barrel and spaced therefrom to form a pocket standing valvemechanism carried by the upper end of said valve anchor, a reciprocat-.n plunger operating in the Working barrel above the Valve mechanism,means for centering the Working barrel Within the stand ing barrel, saidcentering means including a spider formed with legs, rings connectingsaid legs at the upper and lower ends, said legs being supported by theupper end of the Working barrel, the lower ring surrounding the Workingbarrel and the upper ring being anchored in the standing barrel. n

In testimony whereof I have signed my name to this specification in thepresence of tivo subscribing witnesses.
